CloudABI uses a structure called cloudabi_sockstat_t. Think of it as 'struct stat' for sockets. It is used by functions such as getsockname(), getpeername(), some of the getsockopt() values, etc. This change implements the sock_stat_get() system call that returns a copy of this structure. The accept() system call should also return a full copy of this structure eventually, but for now we're only interested in the peer address. Add a TODO() to make sure this is patched up later on.
